It's every parent's worst nightmare but would you know what to do if you found your baby unresponsive and not breathing?

According to the NHS, just under 300 babies die suddenly and unexpectedly every year in the UK.

Should you ever be faced with this situation, it’s important to remain calm and be confident in your actions, but it's also worth familiarising yourself with official medical advice.

St John Ambulance Service has released a number of first aid tips and information to look after your baby, including a step-by-step video on how to give babies CPR.

Below is their official guidance (as stated on their website) about what to do if you find your baby unresponsive or not breathing.

What to look for

If your baby is not responding to you and you think they are unresponsive try to see if they react when you gently tap or flick the sole of their foot. If they do not wake up or respond to you they are likely to be unresponsive.

Check to see if they are still breathing normally. If they are unresponsive and not breathing normally open their airway and check their breathing again by looking for chest movement, listening for the sounds of normal breathing and seeing if you can feel their breath on your cheek.
